Reducibility of higher-order to pairwise interactions: Social impact models on hypergraphs
Jaume Llabrés, Raúl Toral, Maxi San Miguel +1
We show that a general class of social impact models with higher-order interactions on hypergraphs can be exactly reduced to an equivalent model with pairwise interactions on a wei…

Partisan voter model on complex networks: Dynamics of local ordering
Jaume Llabrés, Maxi San Miguel, Raúl Toral
We investigate the processes of local ordering for the partisan voter model on complex networks. In this model, agents hold a binary opinion and a fixed preference that biases upda…

Barrier crossing in a two-state system: Effect of bias and stochastic fields
Sara Oliver-Bonafoux, Raúl Toral, Amitabha Chakrabarti
We study barrier crossing in a two-state system, namely the kinetic Ising model, in the presence of a weak bias field and spatially homogeneous, but time-dependent, Gaussian random…
